MicroLogix-1200-to-PowerFlex-4-ModbusThis second program is based on the first, but uses the Modbus Master protocol available in the latest release of the MicroLogix 1200, as well as a 1761-Net-AIC.

The biggest obstacle in getting this configuration to work was trying to find the polarity of the comm lines (i.e. does + comm on the AIC go to A or B comm on the drive?) as well as realizing all the modbus addresses are offset by 1 (which even Rockwell Drives Div. missed in Rev 1 of the subsequently release tech note).

Since this file was published, Rockwell has release (and fixed) a tech note, and also has an excellent 2004 HOT LAB.
